The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the coming days.
We’ve got a bit of a mixed bag shaping up, but there’s some real quality to be found if you pick your days right. The water temp is sitting at 72°, which is bang on average for this time of year, so no surprises there.
The first real action kicks off Thursday morning at Jaconé. It’s a consistent spot, exposed to the SE, and we’ve got a clean 4ft swell from the SE with a period of 10 seconds. The wind is a light offshore from the NE, so conditions are looking clean. This is a solid, fun-sized wave with moderate energy levels (368) and it’s a great option to start the period. The offshore wind is a major plus here. Crowds can show up sometimes, but it’s worth it.
The swell hangs around into Friday morning, a little smaller at 3ft, but still with that clean offshore NNE breeze. It’s a nice gentle start to the day.
Now, Saturday the 18th sees a bit of a shift. The morning brings a 6ft swell from the ENE, but the period drops to 7 seconds, which is a short-period wind swell. The wind is cross-offshore, so it’s not a write-off, but the energy is a bit lumpy (467). It’s surfable, but not the best of the run.
Sunday the 19th is where you want to be. The morning has 5ft of swell from the ENE with an 8-second period, and the wind is offshore from the NNE. The combined energy is a solid 500, and the forecast says “very good surf conditions.” This is the standout of the first week. The waves will have a bit more punch, and with the offshore wind, it’ll be glassy and clean.
After Sunday, the size drops off into the middle of the week. Monday the 20th still has a decent 6ft morning with offshore wind, but it’s not as clean. By Tuesday and Wednesday, we’re down to knee-to-waist high stuff with weak energy, so it’s a good time to rest the arms.
We hit a bit of a rough patch from Thursday the 23rd through to the end of the month. Strong onshore winds and poor conditions dominate. The swell picks up again but with SW and S winds, it’s messy. There’s a period on Saturday the 25th where the swell hits 6ft to 7ft from the S, but with onshore and cross-shore winds, it’s going to be a bumpy, blown-out mess. The water will be choppy. This setup looks more interesting for kite surfing than paddle surfing.
Now, for the true standout. Mark your calendars for the very end of the period. Thursday the 31st of July is an absolute gem. The morning brings a 7ft S swell with a long period of 12 seconds, and a light offshore NE breeze. The combined energy is a massive 1260 – that’s strong. The conditions are described as excellent for experienced surfers. By the afternoon, the wind goes completely glassy, the swell bumps up to 7ft, and the energy hits 1351. This is a proper groundswell, and it’s going to be powerful. Because it’s long-period, it’ll be best at a point break or reef, but it’s a day for the experts. It’s a long way out, so the forecast is promising but less certain, but it looks like the best wave of the whole outlook.
So, to sum it up: Sunday the 19th is your best bet for the first week, and the 31st of July is the big one to watch if you’ve got the skills.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
